DABBING BRUSH APPARATUS FOR WOOL-COMBING MACHINES SPECIFICATION forming part of Letters Patent N 0. 642,160, dated January 30, 1900. Application filed March 6, 1899- Serial No. 707,936- (No model.)

To all whom it may concern:

Be it known that I, ISAAC RUsHwoRTH, a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented a new and useful Dabbing-Brush Apparatus for W'ool- Oombing Machines, of which the following is a specification.

This invention relates to dabbing-brush apparatus for wool-combing machines; and the object of the invention is to provide a construction wherein the parts can be assembled with rapidity and manufactured at a low cost, and the apparatus is in the nature of an improvement upon that set forth in Letters Patent No. 525,429, granted to me September 4, 1894.

With these ends in view the invention consists in the novel combination of elements and in the construction and arrangement of parts which will be hereinafter more fully described and claimed.

To enable others to understand the inven tion, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a side elevation, partly in section, showing the elements of my invention in their correlative positions. Fig. 2isafront elevation with a portion of the casing removed for the same purpose. Fig. 3 is a horizontal section taken in the line 3 3 of Fig. 1.

Similar reference characters denote corresponding parts in each of the several views.

Certain of the operative parts of the apparatus are inclosed within the casing G, which consists of two parts, as 2 and 3, each in the form of a plate. The back plate 3 is provided with arms 4., located at suitable points in the height thereof and concaved to fit against the eorrespondiugly-shaped face of the vertical pillar or standard 5, bolts being provided to hold the plate 3 in place. The pillar 5 is hollow and incloses the vertical driving-shaft 6, which can be connected in some suitable manner with the driving-pulley 7 secured to the eccentric brush operating shaft 8. These parts may be connected in the manner shown in the Letters Patent heretofore mentioned.

The plates 2 and 3 are separated by a comparatively wide space, in which certain of the operative parts are inclosed, and the plate 2 is provided with a web 0, extending entirely around the outer edge thereof and provided with an inturned flange 10, which can be bolted or otherwise secured to the face of the back plate 3.

The shaft 8 is adapted to turn in bushings l4, fitted in transverse openings in the plates 2 and 3, the latter having annular flanges 16 placed against the adjacent faces of hubs 16,surrounding the bearing-openings, said bushings being held in place through the medium of bolts or screws 15, passed therethrough and into the hubs 16.

Keyed or otherwise secured to the shaft 8 is a pulley 7 for rotating the said shaft, and, as shown in dotted lines, a key is operatively interposed between a part of the pulley and shaft for an obvious purpose and held against displacement by means of a nut 17, engaging the threaded end of the shaft.

The shaft 8 is recessed, as at 30, and therein on said shaft is an eccentric 12 within the plane of the adjacent part of the shaft and which is less in width than the recess to provide opposite grooves 26 and 20', the remaining part of said eccentric being a radiallyextending web 12..

Upon the eccentric 12 is an eccentric-strap 23, carried by an eccentric-arm 20 and having an inwardly-directed flange 31 at one edge which bears against the adjacent edge of the said eccentric and also enters the groove 26 of the recess 30 in the shaft 8. At the opposite side of the eccentric a retaining-ring 22 is applied in the groove 26, held in place bymeans of screws passed therethrough into the strap 23.

To provide for the insertion or application of the strap 23 relatively to the eccentric, the shaft 8, as previously indicated, is recessed adjacent the eccentric 12, as at 30, to receive a filling-block 31, the outer face of which is curved to agree with the curvature of the shaft. This filling-block constitutes, in fact,

a part of the shaft and rotates within the inner bushing 14:, being held in place by screws or other fastening devices and shouldered at its outer end, as at 32, to fit against its i11- closing bushing, the said shouldered end being in proximity to the annular flange of the eccentric-strap, which projects into the portion 26 of the said recess 30. The outer end of the eccentric-arm 20 is provided with a bearing-opening 35 to receive a pivot-bolt 36, which extends through a longitudinal slot 37 in the cap-plate 2 and also through a pivot or journal opening in the upper end of a slide 37', which is reciprocated between the guidestrips 18 on the front side of the face-plate. The slide 37 is provided at its lower end with the usual brush.

The purpose of the casing C is to protect the bearing parts of the apparatus as far as practicable, and it contains oil for the purpose of lubricating the parts, and to prevent the escape of the oil as the eccentric-arm rises splasher-guards 40 are provided and located one above the other, said guards consisting of curved plates or flanges extending inwardly from the front plate 2 and the inner edges of which are located in proximity to the eccentric-arm 20, thereby to prevent the spashing of oil through the opening 37 on the reciprocation of the eccentric-arm.

The plate 2 at the upper side thereof is provided with a depending internal portion 42, having a rabbeted guideway 43 to receive a correspondingly-shaped head 44: of the connecting bolt or pivot 35, and the length of this portion 42 slightly exceeds the length of the working stroke of the eccentric-arm, with which said pivot is connected, whereby the upper end of the arm will be properly guided throughout the complete stroke thereof.

Changes in the form, proportions, size, and minor details of construction within the scope of the invention may be resorted to without sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is 1.
